Brodie Abscess

Brodie abscess is a relatively rare subacute form of osteomyelitis that is difficult to diagnose due to its insidious onset and limited initial systemic response. We present a case of Brodie abscess in a person with knee pain, swelling and antalgic gait. Diagnosis was made initially using plain radiography, this was supported by magnetic resonance imaging and confirmed on bacterial culture of the surgical samples.

Clinical Awareness

Abstract Background Intra-articular venous malformations of the knee are an uncommon cause of unilateral knee pain in children. Timely diagnosis is important because lesions with intrasynovial involvement can lead to joint space hemorrhage and secondary cartilage damage. Objective To describe our tertiary center’s experience of diagnostics and typical magnetic resonance imaging (MRI) findings. Materials and methods A retrospective review of all patients ≤16 years of age managed for intra-articular venous malformations of the knee at our institution between 2002 and 2018. Results Of 14 patients (8 male), the mean age at presentation was 6 years (range: 0–14 years). The most common clinical findings were unilateral knee pain (93%), joint swelling (79%), quadriceps atrophy (50%) and a limited range of motion (29%). Cutaneous manifestations were present in four patients (29%). Contrast-enhanced MRI was available in all cases. After initial MRI, a vascular anomaly etiology had been identified in 11 cases (79%), and correctly reported as a venous malformation in 6 (55%). Three patients received entirely different diagnoses (arthritis, tumor or pigmented villonodular synovitis). Three of seven patients with intrasynovial lesions had established chondropathy at diagnosis. Two patients with lesions of the suprapatellar fat pad had intrasynovial involvement that was not visualised on MRI. Conclusion Although MRI usually permits the diagnosis, clinical awareness of these lesions is important for optimal imaging, accurate interpretation and timely diagnosis. Involvement of the intrasynovial cavity carries a risk of hemarthrosis and progressive chondropathy that may be underestimated by MRI.

Abstract OBJECTIVE AND IMPORTANCE: Ossification of the ligamentum flavum (OLF) is increasingly being recognized as a cause of myeloradiculopathy. However, the cause of such OLF has been identified only occasionally. The purpose of this case report is to highlight one more cause of OLF causing myelopathy. CLINICAL PRESENTATION: Two middle-aged men residing in an area endemic for fluorosis presented with the insidious onset of myelopathy. Clinical examination revealed evidence of thoracic cord compression in both patients. Plain x-rays revealed markedly increased bone density characteristic of fluorosis. Magnetic resonance imaging revealed OLF in the lower thoracic region causing cord compression (at one level in the first patient and at three consecutive levels in the second patient). Plain x-rays of the forearm revealed ossification of the interosseous membrane, which is characteristic of fluorosis. INTERVENTION: Both patients underwent decompressive laminectomy with removal of the OLF. The laminae and ossified yellow ligaments formed one mass of bone, which was removed with rongeurs and drills. After surgery, the first patient demonstrated improvement in motor power, whereas the second patient did not demonstrate any change in neurological status. CONCLUSION: Fluorosis should be entertained in the differential diagnosis of OLF, especially in patients from endemic areas. The magnetic resonance imaging appearance of the spine in such cases is characteristic. In properly selected cases of fluorotic myelopathy, surgery is indicated. However, the prognosis is guarded, and long-term follow-up of these patients is necessary given the nature of the underlying disease.
